摘要：

Induced radionuclides in the chemical reagents collected in the JCO's Wet Chemistry Testing Laboratory were measured using HPGe detectors in the Low Level Radioactivity Laboratory (LLRL) and in Ogoya underground laboratory. Radioactive nuclei produced by neutron capture reactions were detected in most of the reagents. Products of the (n, p) reaction were detected only in Raney-Nickel and metallic powder of stainless steel. Preliminary estimation of the neutron fluence was made on the basis of determinations of radionuclide concentrations. (C) 2000 Elsevier Science Ltd. All rights reserved.
